BERNARR MAGFADDEN, OF NEW YORK, N. Y.

HEATING AND HUMIDIFYING SYSTEM.

Specification of Letters Patent.

Patented J an. 14, 1919.

Application filed April 19', 1917. Serial No. 133,307.

To all whom it may concern:

Be it known that I, BERNARR MAoFAn- DEN, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Heating and Humidifying Systems, of which the following is a specification.

This invention relates to systems for hu- "midifying and heating the air of rooms,

by heat may be extracted from the products of combustion in the chimney either by contact-of said product with water pipes, or also directly with the water to be heated, whereby the products .of combustion are washed and freed from solid matter.

Another-object is to provide a system and radiators whereby the air is humidified and heated by direct contact with water exposed in open troughs'or fountain jets of the radiator.

Another object istoprovide a convenient, efiicient and economical construction for such a radiator.

Another object is to provide a system adaptable to either the open trough radiator 01 the ordinary closed radiators. Y

A further object'is to provide a conveniently constructed economical and eflicient system accomplishing theabove objects.

These and other objects will appear as the description proceeds, and itis particularly noted that, various changes may be made in the construction and details thereof. without departing from the scope of theinvention as claimed. v v

In the accompanying drawing, showing embodiments of t einvention,

Figure 1 is a diagrammatic view showing a vertical section of'a building and the humidifying and heating system partly in elevation and partly in section.

by way of'examplle, one of many possible Fig. 2 is a central vertical sectional view showing the open trough radiator.

The new system is shown applied to .a

building having floors 5, 6, 7, and-a roof 8.".

A hot water heaterg9 is provided in the basement of the building, and discharges P is .combust1on arebr'ought into mtnnate conits products of combustion into the chimney 10.

If the slide dampers 11 and 12 are open, as shown by the'dotted lines, the combustion products pass directly out of the chimney. If, however, the slide damper 11 is closed, and the dampers 14 of the flue pipe 15 are open the hot products of combustion pass through the flue pipe 15 and 'give out to the rooms considerable heat that would,

in ordinary systems, be otherwise wasted.

Water may be introduced inte the system from the city mains through the pipe 16 and valve 18. 7

When' the heat is to be extracted from the products of combustion by direct contactwith the water, the water passes through the pipe 19, the motor driven pump 20 and the pipe 21 to the spray nozzles 22 and 24 in the box-like spray-flue 25, communicating with the upper part of the chimney and havin an outlet flue controlled by the damper 26.

en the damper 26 is open and the damper 12 closed, the. products of combustion pass through the spray flue and are washed and cooled by the sprays from the nozzles 22 and 24, a large er cent. of the heat being carried off in the rip water. The bottom of thespray flue is adapted to hold the drip water from the sprays and the overflow through the pipe 28 to the filter 29 where carbon particles and the like are removed from the water.

. From the filter the 'water passes through the pipes 30 and 31 (the valve. 32 being closed and the valve 33 open) to the heatexchanging coil 34 where the water is fur-. ther heated by the-hot gases of the chimney. From the coil 34 the water passes through the pipe 35 to the heater. 9, the valve 36 being open and the valve 37 closed. The water is additionally heated in the heater- 9 and, the valve 41 being open and the valve 42 being closed, the water passes through the pipe 38 to the radiators 39 and.

40, the latter'to be described more in detail hereafter. passes through the pipes 43, and 44 to the pipe '19 and thence tothe pump 20 thus completing the circuit. p

Both sets of nozzles '22 and 24 are di- From the radiators the water rooted to throw water onto the felts 45 stretched on horizontal bars 46 extending across the spray flue 25,-whei'eby a sinuous provided in which the products of I tact with the water sprayed onto the felts,

thus increasing the heat exchanging capacity of the apparatus.

By means of the valves 48 and 49 any of the radiators 39 or 10 may be cut out of operation.

The radiators 40 have as theirprincipal feature the exchange of heat from the water by direct contact of the water with the air of the room to be heated; These radiators may be constructed in a variety of ways, for instance, as shown in Fig. 2 of the drawing, where the radiator comprises a plurality of annular troughs 50,51, and 52, each provided with an upwardly extending flange 54:, on which rests the trough next above, except in the case of the top trough 52 which supports thereon the bowl 55.

The lowermost trough 50 is provided with supporting legs 56 and an outlet pipe 58 leading to the pipe 44.

Extending across the opening formed by the bottom annular trough 50 is a disk-like web 59 provided with a central perforation through which passes the inlet pipe 60, in turn passing through the bottom of the bowl 55 and terminating with a small orifice for furnishing a spray 61. The pipe 60 also serves for holding together the various sections of the radiator by means of the collar 62 and the nuts 64.

The bowl 5-5 and the-troughs 51 and 52 are provided with lips 65 whereby the water i 'may drip to each trough below, the troughs gradually increasing in diameter down-- wardly for this purpose.

The bowl and the troughs 51 and 52 are provided with small bleed holes 66. For the trough 50, the bleed hole 67 is in the outlet pipe 58. By these bleed holes the water is entirely drained out of the trough when the troughs are to be put out of use, but they are not large enough to interfere with the normal operation of the radiator.

It will be noted that the inlet of the pipe 28 is well above the spray 61 so that there is always suflicient pressure for feeding this spray.

The valve 18 may be left very slightly open to make up for the losses of evaporation. If an excess of water passes into-the spray flue, it may overflow through the overflow pipe 68.

If it be deemed desirable to use the system without heating by direct air and water contact, the damper 12 is opened and the damper 26, the filter valve 69, the pump valve 70 and the valves 36, 41 and 49 are closed. In this case the water passes into. the heater through the pipe 19 and out through the pipe 71, thence through the coil 34:, pipe 7 2, pipe 38, radiators 89, pipe 43, and pipe 19 to the heater, thus completing the circuit, the pipe 38 being. extended tothe expansion tank 74.
